SPECIFICATION forming part of Letters Patent No. 578,121, dated March 2,1897.

Application filed June 29, 1896.

T0 at whom it may concern.-

Be it known that I, CHARLES SPIRo, a citizen of the UnitedStates,r'esiding at New York, in the county of New York, State of NewYork, have invented certain new and useful Improvements in Type -WritingMachines, of which the following is a specification, reference being hadtherein to the accompanying drawings.

This invention relates to type-writing machines, having for its object,among others, to provide an improved machine of the Remington type whichshall be simple in its construction, efficient in operation, durable,and not liable to derangement or injury to any of the parts. I constructthe frame in sections that is, the front, back, and cap are made ofseparable partsso that in case of breakage the frame is not lost, butcan be readily repaired by replacing the broken part. I provide a simpleconstruction and mechanism for inverting or tilting the platen by meansof a key, whereby the work may be readily inspected, the platen beingmounted to automatically return to its normal position when pressureupon the key is removed and to be automatically locked in such normalposition. Novel mechanism is provided for thus looking the parts. Thecarriage is detachably mounted for easy removal for cleaning. I dispenseWith a sliding frame for shifting from lower to upper case and in lieuthereof provide simple mechanism, the carriage having pivotal connectionwith its roller frame, whereby the latter is rocked upon its guiderod asthe carriage is shifted back and forth to change from upper to lowercase, or vice versa. I provide an improved keyboard-lock for preventingprinting of letters one upon another after the end of a line or apredetermined point has been reached, the said lock being adjustable tovary the point of locking and the latter released by the carriage-shiftkey. The platen and line-feed are removabl y mounted to permit of thesubstitution of others when desired. The linefeed pawl is mounted to.bethrown out of mesh automatically to permit of back rotation of theplaten, a roller abutment for the feed dogs or pawls being provided. Ifurther provide an improved simple and accurate paper-feed. Furthermore,I provide a more durable and sim- Serial No. 554,474. (N0 model.)

ple hanger for the type-bars and provide for adjustment thereof in caseof wear. The mechanism for the automatic reversal of the ribbon and foran automatic lateral shift at each reversal thereof is of simple andnovel construction. A simple means is provided for placing the parts inposition for writing upper or lower case characters solely. The tensionfor the keyboard is simplified and conveniently arranged. I havearranged for the easy removal of the ribbon-spools and for the placingof the ribbon in position.

I aim at various other improvements in details of construction and inthe arrangement of the parts, all of which will be more specificallycalled to attention as the description proceeds.

Other objects and advantages of the invention will hereinafter appearandthe novel features thereof will be particularly pointed out in theappended claims.

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon, form a part of thisspecification, and in Which Figure l is a top plan of my improvedtypewriting machine with parts broken away to better disclose otherfeatures.

Like letters of reference indicate like parts throughout the severalviews.

Such elements of a type-writing machine as are not herein specificallydescribed or referred to may be of any well-known or approved form ofconstruction and mounted for operation in the usual manner. Only suchparts are shown as are necessary to a proper understanding of thefeatures constituting the present invention.

Referring now to the details of the drawin gs by letter, A designatesthe frame, which comprises the front A, the body portion A and the rearportion A these three parts being cast or formed separately and nicelyfitted together and detachably united in any suitable manner, as, forinstance, by screws a, whereby when either part becomes broken ordamaged to such an extent as to require its replacement by a new partthe said part may be replaced without loss or discarding of theremainder of the frame. The bod y portion of this frame is formed withthe standards or posts A, adapted to receive suitable yielding pads orfeet a in the usual manner, and adapted also to support the top A whichmay be fixed thereon in any suitable manner, as, for instance, byscrewsa passed through the top and entering the upper ends of the posts. Suchsecuring means are shown in Figs. 1 and 4. This top is formed atopposite ends with the slots A, extending in the direction of the samefrom front to rear, said slots communicating with the open-ended slotto, eX- tending at right angles thereto, the said slots A being for thereception and guidance of the ribbon A and the slots a provide for theintroduction of the ribbon into the slots A by the placing of saidribbon parallel with -the walls of the slots 0 and then bringing itparallel with the walls of the slots A, as will be readily understoodfrom inspection of Fig. 4.

The key-levers B are of known construction and mounted in the usualmanner, 13

being the back transverse rod upon which from sheet metal and comprisesthe base portion and the parallel side bars I), in which are supportedthe journals for the type-bars.

These journals B are arranged, as seen best in Fig. 12, at angles toeach other, so that they practically cross, as indicated in said Fig.12, the said journals of course being upon different vertical planes, asillustrated in Fig. 13, and each hanger supporting two journals andconsequently two type-bars. The ends of the journals are cone-shaped, asseen at b in Fig. 12, the one end being supported in a like bearing inone of the said bars I) of the hanger, while the other extends into andhas a similar bearing in a nut B, which nut is engaged in ascrew-threaded opening in the side bar I) of the hanger, whereby readyadj ustment for wear is provided. The type-bar is provided with a sleeveor boss 13, which receives the journal and upon which it is rigidlysecured. The tail of the type-bar isperforated, as shown at b for thereception of the ligament which connects the same with the key-lever, asusual. The placing of the journals at different angles, as shown,provides for the accommodation of the two typebars on the same hangerand economizes space. The nuts upon the ends of the journals arearranged at opposite ends, as shown, so as to be more readily accessiblefor ad justment when necessary. The hanger is secu red in position uponthe ring A of the top A by means of a screw 1), passed through anopening Z1 in the horizontal portion of the hanger, as seen best in Fig.1.

I deem it expedient to next describe the ribbon-feed and the mechanismfor causing the automatic reversal thereof at each end, as well as alateral shift upon each automatic reversal, and for this purpose specialattention is directed to Figs. 6, '7, 9, 11, and 14, in which the top Ais shown as provided at each end with the depending arms or lugs O, inwhich are journaled the spool-shafts O, as seen best in Figs. 6 and 7,and which spoolshafts carry at one end a beveled gear C adapted to meshwith the smaller beveled gears C on the transverse shaft C, arranged atthe rear of the machine in suitable bearings or lugs C depending fromthe top A of the machine, as seen best in Fig. 14, this latter shaft Cbeing designed to be moved lengthwise in its bearings by mechanismhereinafter described, the ribbon being designed to be fed alongautomatically at each depression of the key-lever in the usual manner.

The main portion of the frame is formed upon opposite sides thereof withthe lugs A", as seen best in Figs. 6, 7, and 14, in which lugs arejournaled to rock the shafts D, one upon each side of the machine, asseen in Fig. 14, these shafts being designed to be held in the lugs inany suitable manner, as, for instance, by the screw shown in Fig. 14,although this is an unessential feature of thee-onstruction. Each ofthese shafts D carries uprights D, which in Figs. 9 and 14 are shown ascurved, and their upper ends are connected by the shaft D on each ofwhich are mounted to slide lengthwise thereof the rollers D which arelines in Fig. 7.

adapted to lie between the heads or flanges-e of the ribbon-spools E, asindicated by dotted These rollers are connected to move together and inthe groove 6. Between said rollers is mounted to work the end or head 6of the arm E which is pivoted at its lower end, as shown at E, to thebase or frame of the machine, as seen in Figs. 6 and 7. These rollersare adapted to bear yieldingly against the ribbon wound upon theribbon-spool, and as the ribbon accumulates thereon the said rollers andthe rocking frame by which they are carried are gradually moved inwardtoward the center of the machine, as will be readily understood. Each ofthese rocking frames carries a spring-arm E (seen in Figs. 6, 7, 9, and14,) the upper end of which is forked to embrace the shaft 0 and adaptedto engage a collar e thereon, as seen best in Fig. 14. The-side bar orupright of the rocking frame is provided with an extension 61, as seenbest in Fig. 9, from which projects a lateral pin 61', as seen in Figs.9 and 14, against which the forked end of the spring-arm engages, asseen in Fig. 14. Pro-- jecting laterally from a depending lug E on thetop A of the machine is a projection or screw 6 on which is pivotallymounted an arm E, as seen in Figs. 6 and 14. This arm is adapted to restupon the collars e on the shaft 0 alternately-that is, when the said armon one side of the machine is riding upon its collar the arm upon theother side is engaging against the face of the collar upon the oppositeside, as seen best in Fig. 14.

In operation, as the ribbon is wound upon the one spool and unwound fromthe other, as it accumulates upon the former the rollers D of the spoolwhich is receiving the ribbon will be gradually forced away therefrom,while the rollers upon the other side will gradually move outward as theribbon on the said spool is unwound. Now as the rocking frame carryingsaid rollers is moved inward toward the center of the machine thetapered or beveled end of the extension cl of one of the uprights of therocking frame is gradually engaged under the free end of the arm E andthe latter is lifted from its engagement with the i11- ner face of itscollar 6 and in the continued movement of the rocking frame the said arm11 is moved up over the said collar, as indicated at the left of Fig.14, in which view the ribbon-spool upon the left is receiving the ribbonand is nearly full, while from that upon the right the ribbon is beingunwound. As seen in said Fig. 14, the ribbon has just been reversed, theshaft C having been moved to the right so its beveled pinion would meshwith the beveled pinion O on the shaft O at the right of the machine insaid Fig. 14.

As soon as the arm is raised clear of the collar 6 the spring-arm Ecomes into play and forces the shaft 0 endwise against the action of thespring E at the opposite side of the machine, and shouldthe pinion C forany reason fail to immediately engage with its pinion C the continuedmovement of the rocking frame will cause its spring-arm E to force thesaid pinion into engagement with its mate. It will of course be readilyunderstood that the same operation occurs when the ribbon is unwoundfrom the spool on the left and is wound upon that on the right in Fig.14.

In order to provide an automatic lateral shiftof the ribbon at eachreversal thereof, as above described, so that the entire surface of theribbon may be brought into operative position and thus its entiresurface utilized, I have provided the means illustrated more fully inFigs. 6, 7, 9, and 11, to which special attention is now called. Thearms E the upper ends of which engage in the grooves of thepressure-rollers D are connected by or formed integral with theconnecting portion E, as seen best in Figs. 9 and 14, and projectinglaterally from one of these arms or uprights E is the yoke E between thebif urcations of which is mounted to work a cam E (shown best in Fig.7,) this cam being fast upon a shaft E", vertically disposed and mountedfor rotation ina suitable bearing on the frame. The upper end of thisshaft is formed with or carries a ratchet-wheel Dflwhich, as seen inFigs. 7 and 9, is mounted to revolve in a horizontal plane, and withthis ratchet engages a pawl Diwhich is pivotally mounted upon a rod D,which connects the uprights D of the rocking frame at a point betweentheir upper and lower ends, as seen best in Figs. 7 and 9. The operationof this part of the invention will be readily understood and is asfollows:

At each reversal of the ribbon as it nears its end the rocking framecarrying the pressure-spools is moved sufficiently to cause the pawl Dto move the ratchet D one tooth. This movement of the ratchet causes theshaft F. to be moved so that movement of the cam thereon engagingbetween the bifurcations of the yoke on the arm E will move the latterlaterally'sufiiciently to move the ribbon-spools laterally on theirshafts, so as to bring a different surface of the ribbon into operativeposition. The ribbon-spools, as will be readily understood, are mountedfor movement lengthwise of their shaft and should move by the engagementof the pressure-rollers D the latter engaging the flanges or heads ofthe ribbon-spools between which they are mounted to work. The ends ofthe ribbon-spool shafts are free, so that the spools may be readilyplaced thereon or removed when it is desired to replace them. by a newribbon and spool. It will thus be seen that not only is the direction ofthe movement of the ribbon automatically reversed at each end of itsmovement, but at each such reversal the ribbon is shifted laterally, soas to bring a different lateral surface thereof into operative position.

The carriage is given the usual step-by-step feed in the ordinary way,the feed-pawls F F (seen in Fig. 4) being mounted on the block F and inorder to provide a firm abutment for said block to prevent injurythereto and to the pawls by the movement of the carriage I provide theblock F upon which is mounted the friction-roller F on a suitablevertical pivot, as seen in Fig. 4, by which means I not only provide afirm abutment for the block carrying the feed-pawls, but materiallyreduce the friction, the said friction-roller being so mounted as to beengaged by the block F in its reciprocatory movements. The ordinarystep-by-step feed-rack F", with which the pawls F F engage, is shown asthrown back in Fig. 4 and is shown in operative position in Fig. 1. Itis provided with ears f sleeved upon the guide-rod F.

The rear guide-rod F is mounted in lugs a on the rear portion of the topof the machine, as seen in Figs. 6 and '7. The front guide-rod G issecured to and mounted upon the arms G, secured to the rocking shaft Gwhich is mounted in suitable lugs or supports depending from the underside of the top A of the machine near the front, and this rod and theuprights are designed to be moved backward and forward to shift fromupper to lower case, or vice versa, by simple and novel meansillustrated clearly in Fig. 7, in which a finger-lever G is shown whichis pivoted upon the shaft G in any suitable manner, and this lever isprovided with a cutaway portion 9 and shoulders g7 g all as clearlyshown in Fig. 7, and the upright or arm G upon this side of themachineis provided with a projecting pin G, designed to be engaged byeither of the said shoulders to hold the front shift-rod in either itsbackward or forward position. A spring G is employed, one end of whichis connected in any suitable manner to some fixed part, as the top ofthe machine, and its other end engaging a stud g 011 the lever G asclearly shown in Fig. 7. The arm G upon this side of the machine isprovided with a rearwardly-extending arm G, the inner end of which isconnected by a link or ligament G with a shift-key lever G, as indicatedby dotted lines in Fig. '7, whereby the carriage may be shifted to upperor lower case by the manipulation of said key.

H, Figs. 1 and 4C, is the margin-regulator rack-bar, suit-ably mountedupon the top of the machine an d carrying at its center the index-fingeror pointer II. 11 is a stop slidingly mounted upon this rack-bar andprovided with a spring-actuated pawl H de signed to engage with theteeth of the rack, this stop being adjustable to regulate the margin,the carriage being provided with a depending part or abutment to engagetherewith, as will be readily understood. Slidingly mounted upon thisrack-bar upon the opposite side of the center is a stop H having aspring-actuated pawl H for engagement with the teeth of the rack anddesigned to be adj ustable to cause the bell to ring at anypredetermined point, the stop H for engagement therewith being pivotallymounted, as at h, on the platen-carriage and designed to engage thebell-hammer H pivotally mounted upon the carriage and designed to soundthe bell H in the usual way. The stops H H, either or both, may bearranged to be manipulated from the front of the front guiderod in anysuitable manner so that they may be adjusted without lifting thecarriage.

In Fig. 4 I have shown the block or stop H as provided with an arm h,while the pawl ll is provided with an extension or arm 76*, by themovement of which in the direction of the arrow in said Fig. 4c the pawlwill be disengaged from the rack, when the block or stop may be moved ineither direction by the arm h, and when pressure is removed from the armh the spring of the pawl forces the latter into contact or engagementwith the rack, and thus locks the block or stop in its adjustedposition.

I is the j ump-feed or column regulator rackbar, suitably mounted at therear of the machine, as seen best in Fig. 4, and provided with theremovable pin i, of usual construction, adapted to be inserted into anyone of the holes in the rack to regulate the space between the columns,while upon the carriage is pivotally mounted an arm or lover I, pivotedat t" and adapted to be thrown down into the path of the said pin, so asto engage the sam e when tabulated work is to be performed.

I is an arm projecting from the usual stepby-step feed-rack F andadapted to be engaged by the arm 1, pivotally mounted at the left-handside of the carriage and its front end terminating in a finger or thumbpiece 1 as shown best in Fig. 1, by pressure upon which the rear end ofthe arm I is brought against the under side of the arm I and therack-bar F lifted from engagement with the feed-pawls, so that thecarriage may be moved in either direction, as may be desired.

J is the platen, of usual construction, and J is the roll between whichand the platen the paper is designed to pass. J is the scale holding theroll up by means of the springs J connected as shown in Fig. 10, so thatthe platen and roll are kept in contact for feeding the paper, the scalebeing arranged as shown, so as to practically cover the roll J, asshown, the scale and the roll being both mounted in the end platesj ofthe frame, said end plates being connected by the back connecting-bar],as seen in Figs. 16 and 17.

J is a bar or rod which extends from one side to the other of theplaten-fra1ne and is detachably connected to the end plates j in anysuitable manner, as seen in Fig. 16. On this red are the guide-springs Jone at each end, which maybe arranged as seen in Fig. 16, where they areshown as attached at one end to the rod J 4 and at the other end to thescale J the said guide-springsj ust barely touching the platen on theline of printing; or these springs may be arranged as shown in Figs. 1and 2, where they are shown as free at the end be- IIO neath the platen,while the other end is attached to the rod J 4 andis rendered adjustableby means of a screw j passed through the said rod or bearing upon thespring between its front bend and the platen, as clearlyshown in Fig. 2.When paper is introduced between the platen and the roller, the scale Jis depressed to allow of the free passage of the pa per between theplaten and the guide-sprin gs J ,and when the paper has been fedforward,so that the same is no longer in contact with the roll J, thenthe tension on the scale J 2 presses the guide-springs J up against thepaper and holds it there to allow of printing to the very lower edge ofthe paper, whereby the last line of printing on the paper will bestraight and parallel withthe precedinglines. On the rod .1, I mountfrictionally the clamp or sliding piece J which is preferably blankedout and formed with earsj to receive the pin as seen in Figs. 16 and 17.On this pin is pivoted the curved spring-piece J which is also providedwith ears j for this purpose, as seen best in Fig. 16, and on theconcave surface of this piece J I mount the curved piece J so that itmay be slid along beneath the piece J and fastened either at the extremetop, as

shown in the drawings, or at a point where the small roll 9' carried bythe lower end of the piece J may be brought into contact with the rollJ. This sliding movement may be provided for in any suitable manner, inthis instance being shown as a thumb-nutj secured in the under piece Jand passing through coincident slots j in the curved pieces J and J asclearly shown in Fig. 16.

The piece J 7 is tensioned by the spring J as seen best in Fig. 16,which is arranged between the ears thereof around the pin 3' so that theroll 7' which is loosely pivoted in the ears formed at the lower end ofthe piece J may always rest in contact with the platen, as seen in Fig.17. Now when the paper is introduced the guide-springs J 5 carry thepaper along until the top edge nearly reaches the roll j when thepressure upon the thumbnut j tilts the roll 3' away from the platen andallows the insertion underneath of the paper without lifting up of thecarriage, and after the lower edge of the paper has left the roll J thenthe roll 9' acts as the feed to allow of writing to the very bottom edgeof the paper, as will be readily understood.

When it is desired to write upon envelops, the sliding piece J is slidalong upon the rod J where it will allow'the envelop to be'taken toallow of writing as much as may be desired on the envelop. After suchadjustment the piece J 8 is slid down, so that the rolls 7' and J are incontact, when said piece is fastened in such position by the thumb-nut.It will thus be seen that the envelop need only be introduced into thecarriageand fed along writing. The shaft or journals j" of the platenare passed through and rotatably mounted in the end pieces j of theplaten-frame, and upon one end thereof is secured the bell H the edge ofwhich is milled, as shown in Fig. 1, and by which the platen may berotated by hand, as may be desired. The extended ends of the platenshaft or journals are removably mounted in the carriage K, and in Figs.1 and 3 I have shown one means of thus detachably holding the saidplaten journals. In this form the carriage is formed with the lugs k,undercut or shoulders, as seen in Fig. 3,while upon lugs k, to the rearthereof, are detachably pivotally mounted, as by the screws 10 the armsK extending parallel with the end bars of the carriage, their forwardends being provided with depressions or sockets K as shown best in Fig.3, to receive the journals of the platen, the said arms being extendedrearward of their pivots and downwardly to engage stops k on thecarriage. Between the pivot and the journal-receiving socket there isarranged a spring K upon which the said arm rests, and this spring isarranged in a socket 70 formed on the carriage K, as seen in Fig. 3. Bydepressing the arms K into position indicated in full lines in Fig. 3the platen-journals may be readily removed. They may be readily insertedby placing them upon the front ends of the arms K, when by pressurethereon the journals can be easily forced into position, and when'oncein place the springs force the arms up and lock the platen againstaccidental displacement, but permitting of its easy rotation. Theplaten-carriage K is provided at its front side with the rollers Kadapted to run upon the front rod G, as shown. The carriage K hasextending from its rear portion the rearwardly-extending perforated earsK, as clearly shown in Fig. 1,which are detachably secured to so as tomove with the carrier-frame L, which consists of the boxes or frames L,in which are journaled the axes Z of the rollers L which ride upon therear guide rOd E the said ears being detachably secured to the boxes, inthis instance by the thumb-screws l, as seen best in Fig. 1.

' The boxes L are formed with ears or lugs Z perforated to receive andwhich ride upon the rear guide-rod F as seen best in Fig. 4, where thecarriage and platen are removed and the step-by-step feed rack-bar F andthe carrier-frame are thrown back in order to better disclose otherparts.

- The means employed forconnecting the ears of the frame K with theboxes L permit of the pivotal movement of the carrier-frame L, whichmovement is limited in its downward direction by means of the pins 1projecting from the said frames or boxes L and engaging upon the lugs lof the rear portion of the carriage K, as clearly illustrated in Fig. 1.

By removal of the thumb-screw Z the frame K with all its accessories canbe removed for the purpose of cleaning or otherwise. In shifting thecarriage to change from upper to lower case, or vice versa, the carriageK and its ac cessories moves in a horizontal plane, while thecarrier-frame L and its boxes and rollers rocks upon the rear rod Fturning upon the screws Z as a pivot. To further guide the carriage inits back-and-forth movements when it is shifted for upper or lower caseletters, I provide the bifurcated guide-arm L secured to the under sideof the rear portion of said carriage, loosely embracing a guide-screw orother means L secured to the upper face of the ordinary step-bystep feedrack F as shown best in Fig. 1.

Fast upon the platen shaft or journal is the ratchet M, (seen best inFigs. 1 and 5,) and the platen is designed to be rotated, when required,by means of the lever M, pivoted at m on a lug or riser on the carriageK, the said lever having an extension m beyond its pivot and beyond thejournal of the platen, as seen in Fig. 5, and to the end thereof ispivoted, as at 971 the pawl M the upper end of which is hooked, as seenat m in Fig. 5, and extended into the plane of the ratchet-wheel, sothat by manipulation of the lever M the ratchet-wheel may be turned oneor more teeth and the platen revolved. A spring m connects at one endwith the pawl and at the other end fastened around the pivot of thesame, as seen in Fig. 5. The outer face of the pawl is provided with acam portion m adapted to engage a pin or projection m on the carriage K,which serves to normally hold the tooth end of the pawl out ofengagement with the ratchet, but when the lever M is moved on its pivotthe said cam moves under an engagement with said pin, thereby bringingthe tooth end of the pawl into engagement with the ratchet when thefurther movement of the lever M rotates the platen. Then pressure isremoved from the lever M, the parts return to their normal position, thecam portion engaging under the pin m and throwing the tooth end of theratchet away from and out of engagement with the ratchet.

The limit of movement of the platen is regulated by the readableline-space-regulating device seen best in Figs. l and 10, in which thelever M is shown as provided with an upwardly-projeeting bearing orstandard M which is bored from front to rear, and in this bore isarranged a rotatable regulator M which is provided with acircumferential groove M in which works the pin or screw M (see Fig.10,) which permits of rotation of the regulator M but holds it againstendwise movement. The inner end of this regulator is provided with aseries of notches m in steps, as seen in Fig. 5, the other end of theregulatorbeing provided with a collar and shoulder m bearing against theface of the extension M and provided with a series of slight depressionsM into any one of which is designed to engage the pin M the upper end ofwhich is rounded or pointed, so as to readily slip into the depression,the said pin being mounted for vertical movement in a socket in theextension M being seated upon a spring M located in said socket, whichserves to normally keep the pin uppermost, but permitting of depressionthereof when the regulator is turned. The outer end of this regulator ispolygonal inform, as seen in Fig. 10, and upon its faces aredesignating-characters, as seen in Fig. 10. By rotation of thisregulator the desired notch in its inner end may be brought intoposition to be actuated by the engaging means therefor, which will soonbe described, and by means of which the platen is permitted to be turnedone, two, or three or more teeth bya single manipulation of the lever M,the pin M readily seeking its depression and holding the regulatoragainst farther movement accidentally. The inner end of this regulatoris designed to be engaged by the lever N, pivoted at 'n on one of theend plates j of the platen-carriage, being provided with a spring 72, asseen in Fig. 5, and having a curved extension N, in the free end ofwhich is journaled a roller N arranged in vertical line with and adaptedto bear against the ratchet M to prevent retrogade movement thereofaccidentally, butpermitting, through the resiliency of its springlevers,rotation of the platen by hand when desired. The vertical face of thislever N is arranged in the path of and designed to be engaged by thenotch or'notches of the regulator as the lever M is manipulated torevolve the platen. The platen and its carrier, together with theratchet, and the lever N, with its roller and spring, are all removablebodily from the carriage, when desired, by the means heretoforedescribed and shown in Fig. 3.

O is the paper-table. It is detachably conn ected with the end plates jof the platen carrier or frame by means of the pins 0 at the endsthereof, which are detachably engaged in openings 0 in the rear ends ofthe said end pieces j, as seen in Figs. 1 and 2. The rear edge of thepaper table is engaged detachably in the free ends of the arms 0, whichare pivotal] y mounted on a shaft P, mounted in the curved plates P,which are fast upon said shaft, the shaft and plates being designed tomove pivotally, the inner faces of the curved plates P being providedwith pins 19, between which the arms 0 work, whereby the latter have alimited play or movement of themselves independent of their movement ofthe curved plates. The plates P are further connected by the rod P withwhich rod is designed to be detachably engaged by the upper hooked end29 of the arm P the lower end of which is pivotally connected, as at 19with the lugs 19*, Fig. 15, extending upward from the rear cross-rod Pof the bail P, which is detachably mounted at its forward end upon therod P suitably supported in the frame A near the front, as seen best inFig. 8. This bail is shown in Fig. 15 as provided with bosses oranalogous devices 19 sleeved upon the rod P and held in position by theset-screws 19, wherebythe same may be readily removed when desired, therod P being also removably supported in its bearings on the frame. Thisbail is connected at one end with a special key-lever P by means of theligament or link 13 which is pivotally connected at both ends, the saidspecial key-lever P extending to the front of the machine and by themanipulation of which the platen is tilted so that the writing may bereadily inspected. In Fig. 8 the parts are shown in the position whichthey occupy when the said le- Ver is depressed and the platen has beentilted. In order to lock the parts in their normal position during theprocess of writing, I extend one of the pins 0 on the end of thepaper-table, as seen in Fig. 5, with which is designed to engage thehooked end q of the lever Q, pivoted at g on the end of the carriage K,and at its free end carrying a roller Q, with which the cam portion P ofthe curved plate P. at that end is designed to engage when the lever Pis depressed to tilt the platen, thus throwing the hooked end q of thelever Q out of engagement with the extended end of the pin 0 andallowing the platen to be tilted and the parts to assume the position inwhich they are shown in Fig. 8. A spring (1 is provided upon this leverto normally hold it in engagement with the said pin, as

seen in Fig. 5, and a spring Q is provided,

as shown in Fig. 8, acting upon the shaft P to aid in returning theplaten and paper-table v to their normal position as soon as pressure isrelieved from the lever P The curved plate P at the left-hand end of themachine is provided with a finger-lever P by means of which the platenmay be tilted by hand when desired without manipulation of the lever P7.

In order to lock the keys against actuation when the end of a line or apredetermined point is reached, and thus prevent the writing of oneletter upon another, I attach to'the universal bail R, which of courseis actuated by the space-bar R as well as at the depression of eachkey-lever, a 1*odR vertically disposed and adj ustably connected withsaid universal bail, as seen in Fig. 7, and the upper end of this rod isadjustably and detachably connected with a headed projection R which isadapted to work easily in an opening in the top A of the machine, asshown, while pivoted at the rear of the machine, as at s, is an arm S ofsuch a thickness as to be readily forced under the head of the part Rwhen the latter is in its uppermost position, as seen in Fig. 7, aspring S being provided, one end being attached to the said arm and theother end free and working against a pin 5 on the top A of the frame, asseen best in Fig. 4. The arm S is pivoted upon its upper face near itsfree end with a pin 5 (shown in Figs. 4 and 7,) with which pin isdesigned to engage the forked arm T, depending from the rear of thecarriage K, and, as shown in Figs. 1 and 8, adjustably mounted upon arod or bar T,

carried upon the said carriage K and designed to be adjusted to bringthe said forked arm so that it will engage with the pin of the arm S ata predetermined point in the movement of the carriage, and as said armengages the pin it moves the arm S with it until the latter is movedunder the head of the pin or part R as seen in Fig. '7, and thus lockingthe carriage against movement and the key-levers against depressionsufficient to force the type against the platen. When it is desired torelease the arm S, the shift-lever is depressed and as the carriage ismoved rearward the opening in the forked arm is brought coincident withthe pin 8 on the arm S and when the same becomes coincident the spring Sforces the arm S in the direction of the arrow in Fig. 4, consequentlyreleasing it from engagement with the head of the part R The spring forpropelling the carriage forward is of well-known construction, as is therying the dogs or pawls F by a spring U, as

seen in Fig. 6. Adjustment of this screw regulates the tension of thedogs. This means is placed in amost convenient position and is easy ofmanipulation.
